This sometimes happens to me when I get an incoming phone call. I try to slide to answer, but it only slides half way and then the slider jumps back to the beginning. It's frustrating because I basically miss the call.

This is happening to my wife as well on her 2G. With a slight difference.

The slider bar will appear for a few seconds in it's locked state, the rotating timer wheel will appear briefly in the center of the screen, then the screen will go dark for a few seconds. It will continue to cycle like this for about 5 minutes or so.

Then the Apple will appear as if it's restarting, then promptly powers back up into the same locked state.

Repeat.

I cannot turn the phone off, and iTunes doesn't seem to want to give me the option to restore from backup.

This happened at the last possible instant of updating to 3.0 (This is my wife's phone, I had no problem updating my 2G.

oh ok. good i thought it was only me and i would have to restore as a brand new iphone. but i did restore it and did my back up. lets see if it fixed it, but its probably a bug. i think it did happen in 2.2.1 also but not sure. it may be that i didn't turn off my phone for a while when it happened in 2.2.1 but with 3.0 it did it once. so lets see. glad im not the only one.
